MOIJD-ALINING DEVICE.

Specification of Letters Patent.

Application filed November 15, 1916. Serial No. 131,390.

. I '0 all whom it may concern a conveyor belt (not shown).

Be it known that I, l'lOHER J. Herr. a citizen of the United States, residing at .l.)etroit, county of Wayne, and State of Mich gen, have invented certain new and useful Improvements in lllold-Alining Devices, of which the following is a. full, clear, and exact descri iition.

This invention relates to 'lllOltl ttlll'llng devices and with respect to its more specific flcatures to an alining device employed for centering molds in a. vulcanizmg press-- chamber.

The principal ol'iject of the invention is to provide a device of the kind (lEStilll'Jl-ktl which shall guide mold to aiii position and having; laced all it. other object of the is to pro. a device of the kind llltnl ed ivh be adjusted so that molds of va may he. aiined and held in p051 equal precision.

lo the accompanying dra ings ih which one -of the various pos' ie cml'iodimeiuze of the invention is shown,

Figure 1 reprcsentsa sectional plan view of a vulcanizing press embodying my in vention, the section being taken on line 1 d, of F ig, 1,; I

Fig. 2 represents a partial sectional elevation of the apparatus shown in l; and

Fig. 3 is an enlargeddetail view of an. alining member and the means for securing L l on u it m the side of the press chamber.

M mite-d in the interior of the press-chamber is a hydraulically operated platen 4 adapted to support molds 5 which are delivered from a devlce 6 adapted to unload the molds froin Projecting from the inside of the chamber are three narrow upright brackets 7 here shown as equi-distantly spaced and projecting a su-lli" cient'distance into the chamber to contact with the sides of molds 5 to serve as alin- Eng members therefor; The lower portion of each bracket 1s retained by a U-sha -d" Patented Feb. 19, 1918.

support 8 which is bolted to the interior of the chamber 1. The upper portion of each bracket is provided with a hole which'when to contact with the sides of the mold for s1 tirllllllllilllji its entire depth when the lattcr is in position. The platen 4 is notched to permit the brackets to passthercthrough.

In operation the molds are delivered by unloader 6 to the press and travel by momentum across the mouth thereof tl'icy contact with the three brackets along whose inclined faces they move until they come to rest upon the floor ol' the platen or uponthe preceding mold, with their sides in contact with the faces of the brackets. ,Vhen one mold is positioned the platen is lowered in the usual manner to permit the reception of another mold which is similarly alined and so on until the chamber is filled.

/' It will be observed according to the construction outlined that the brackets 7 not only guide molds to alined position but hold them in that position until the platen is moved for the reception of the next mold. Further, brackets projecting various dis- 'tances into the cl'iainberrnay be employed thereby permitting alincmcnt of molds of W gi en size, and it will be observed that e i'l'iebrackets contact with the sides of the molds along substantially tangential. lines only, that molds of various sizes may. be alined with equal precision.- v

Having thus described my invention what I claim and desire to protect by Letters Pittent is 1. In an apparatus of the kind described, in combination, a chamber adapted to receive molds, a plurality of brackets s aced apart and secured to the side wall 0 said c 'c mber and adapted to engage the molds t iine them when receivedin the chamber,

molds, a table exterior to and inclined to ard said vulcanizer for supporting the molds being fed thereto and having its lower edge at approximately the height of the mouth of said shell when in charging position, and a lurality 01 devices for centering the moles 111 said shell, said devices be ing secured at fixed positions to the interior,

of the shell at its upper edge and below its mouth to permit uninterrupted passage of the molds into said mouth, said devices extending down the wall of said shell to am proximately :1 distance equal to the height of a mold.

3. In a vulcanizing press a head, a shell,

-said head and shell being adapted for relative moven'ient to provide an open space tlu-rehetween for charging the press with molds, a platen for supporting a column of molds, a table exterior to and inclined toward said vulcanizer for supporting the molds being fed thereto and having its lower edge at approximately the height of the mouth of said shell when in charging position, and a plurality of devices for centering the molds in said shell, said devices be ing detachahly secured at fixed positions to the interior of the shell at its upper edge and below its mouth to permit uninterrupted passage of the molds into said nouth said devices extending down the Wall of said shell to approximately a distance equal to the height of a mold.
